Notice that the period is placed after the word _thyself_ and is
followed by the quotation marks.
"We can easily rout the enemy," declared the speaker.
Notice that the comma is placed after _enemy_, and before the quotation
marks.
+554.+ The Interrogation Point and the Exclamation Point are placed
within the quotation marks if they refer _only_ to the words quoted, but
if they belong to the entire sentence they should be placed outside the
quotation marks. For example:
He said, "Will you come now?"
Did he say, "Will you come now"?
He said, "What a beautiful night!"
How wonderfully inspiring is Walt Whitman's poem, "The Song of the
Open Road"!
+555.+ Sometimes parenthetical or explanatory words are inserted within
a quotation. These words should be set off by commas, and both parts of
the quotation enclosed in quotation marks. For example:
"I am aware," he said, "that you do not agree with me."
"But why," the speaker was asked, "should you make such a statement?"
"I do not believe," he replied, "that you have understood me."
